embodiment 1
[0038]In this embodiment, a powdery electrolyte salt is used. The powdery electrolyte salt can be obtained, for example, by crushing a massive electrolyte salt with a pulverizer or by spraying molten salt to a cold space to solidify it.
[0039]The powdery electrolyte salt is spread on the surface of a first separator horizontally laid. Then, a first electrode (negative or positive electrode) is laid on the separator, and the powdery electrolyte salt is spread on the surface of the first electrode. Then, a second separator is laid on the first electrode, and the powdery electrolyte salt is spread on the surface of the second separator. Then, a second electrode (positive or negative electrode) is laid on the second separator, and the powdery electrolyte salt is spread on the surface of the second electrode. Subsequently, the same process is repeated to obtain an electrode laminate with a desired number of layers.
[0040]In another method, powdery electrolyte salt is dissolved in a general...
embodiment 2
[0045]In this embodiment, a semisolid or liquid electrolyte salt is used. Semisolid electrolyte salt can be obtained by heating the above described powdery electrolyte salt to an extent that it is not completely dissolved. That is, the semisolid means a solid-liquid mixture state with a relatively high viscosity including a semi-coagulated state. In addition, the liquid electrolyte salt can be obtained by melting the electrolyte salt through heating. The electrolyte salt can also be rendered semisolid by adjusting the formulation of each component in the electrolyte salt.
[0046]The semisolid or liquid electrolyte salt is applied to the surfaces of the electrodes and the like by any application means such as a brush, an application roller, a rolling coater, a bar coater, a doctor blade, a wire bar, a screen, and a discharger. In this case, it is not necessary to apply the electrolyte salt to the whole surfaces of the electrodes and the like. For example, the electrolyte salt may be ap...
embodiment 3
[0048]In this embodiment, the semisolid or liquid electrolyte salt is applied to the surfaces of the electrodes and the like by using a spraying device. The amount of application can be controlled by adjusting the temperature of the electrolyte salt, the amount and time of spray.
[0049]Subsequently, an electrode laminate is formed using the electrodes and the like to which the electrolyte salt is applied, and the laminate is housed in the battery case, then the battery case is sealed.
